Application filed October 24, 1913. Serial its. 797,119.

-at Akron. in the county of Summit and" State 'of Ohio, have invented new and useful Improvements in Tires, of which the following is a specitication.

This invention relates to improvements in what are known as block tires, and the object of the invention is to provide a ti're composed. a plurality. ot' blocks each 01"' which comprises a body of elastic materia-l, such, for instance, as rubber, and each mounted on an individual metallic plate, allA plates being provided with means to permit theirl inter-engagement when seated on a` wheel rim.

Further objects of the -invention are to lfashion each plate and the corresponding block held thereby in the form of a triangle with the angles thereof rounded and with the blocks disposed with their apices alternately arranged with respect to the bases of coadjacent blocks thereby providing a circii1niierentially-extending series of roadengaging elastic blocks each mounted on its respective base plate with the points or apices arraugedin alternating relation with respect to coadjacent blocks.

A further object. is to form the. inner 'face oi each of the u'ietallic plates on which the blocks are seated, concave. so as to allow only three points of contact between the plates tto 'and the telly-band ou wbieh they are mounted, these contact points beingarranged at the angles nl the blocks so that the plates are adapted to tit bands oi different diameters, and Seat perfectly thereon.

l/Vith the foregoing and other objects in View, the invention consists in the novel construction, combination and arrangement of parts constituting the invention to be hercinafter specifically described and illustrated in the accompanying drawings which form a part hereof wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and I modifications can be resorted to which come within the scope of the matter hereinafter claimed.

ln the drawings in which similar reterence numerals ind icate like parts in the diiferent figures, Figure l, is a plan view of a section of the rim portion ot' a vehicle wheel equipped with a tire embodying this invention; Fig. 2, is a transvmso sectional view of Fig. l on line X. thereof; Fig. 3, is a transverse sectional View of the rim portion of a vehicle wheel showing a bloclrand its plate, also a section; and, Fig. 4, is a plan View of a plate embodying this invention.

Referring to the drawings in detail, the

referencer numeral l denotes the telly of a y,vehicle wheel on which is mounted the usual f' feyily bandi 9 and along the sides-o the wheel are positioned annular rings 8 provided with inturned" c lencher flanges i of zordinary type 'and constituting tire-holding means.

The annular rings 3 are secured to the side faces of theL wheel through the medium of cross bolts 5 in the ordinary way. The channel or seat for the tire, hereinbefore described, is common` and a further description thereof 1s believed to be unnecessary.

The tire which forms the primary portion of this invention embodies a plurality of blocks 6 preferably triangular 1n form and termed of elastic material, and also formed with their inner portions provided atf? `with hard rubber for the reason that the blocks are adapted to besecured by vulcanization to metallic plates,`and as the soft rubber of the treads of the blocks does not vulcanize successfully to the metallic plate, an interposed layer ot' hard rubber overcomes this objection by adording perfect union with the sott rubber of the tread 6 and intimately unites with the metallic plates ou which the blocks are mounted. I

ln practice, the. angles or corners of the Each of the blocks is mounted on a plate approximately triangular in form and each plate is provided in its upper face with a. plurality ot' recesses 9 into which the rub- 'ber of the tire enters and clenches or is anchored. Each of the plates is triangularlyformed and comprises a base l() and an apex 11, both of which are rounded to fit under and be engaged by the inturned clencher langes 4 of the tire-retaining, rings 3. A.

sol

portion of the plates, for instance, A, B, etc.,

(sce Fig. 2) are provided with lateral grooves 12 and the interposed or alternating plates are provided with projecting' tongues or ridges 13 adapted to interengage with the lgrooves 12 in the coadjacent plates. The blocks are so arranged on the telly-band 2 that the apices of every alternate block extends laterally in the same direction and alternate, wirv respect to the bases of contiguous blocks When positioned on a felly-band the plates C provided with the tongues or ridges ,13 are-interposed between the plates which bear the blocks A and B, for instance, and these latter are provided with lateral grooves, so that all of the plates throughout the circumference of the fellyband are caused to interengage. And if, for instance, there is a slight variation in the circumference ofthe felly-band on which the blocks are mounted, the Wedging action setup by the intcrengagement of the triangularly shaped blocks 'with each other Will cause them to snugly engage and interlock as the tire-retaining rings 3 are clamped toward each other by the bolts 5. The curved ends 10 and 11 of the plates Will engage under the over-hanging clencher flanges 4 and be thereby locked inposition and as there is a tongue and groove or groove and channel. engagement between all of the blocks, the

. blocks will be held in position on the face of the fel'ly-band and it is obvious that any slight discrepancy or excess of material in the blocks when placed on the outer face of the felly-band will be taken care of by the wedging action set up in positioning the plates and effecting their interengagement one With another. In order to form these plates so that they will fit the Wheels of varying diameters, the inner face of the blocks are formed concave with inwardlyextending bearing lugs or feet 14 on their inner faces which gives three points of contact for each plate on the outer face of the felly-band, that is to say, there Will be an in- Wardly-turned foot or lug at the apex of each corner of each triangularlyshaped block, thereby providing three points of contact or feet for supporting plates.

It will be obvious that in order to constitute a tire in accordance With this invention,

two lstyles of plates for the reception of blocks Will be needed. That is, one plate, for instance, Will be provided on both its lateral faces with grooves and the next and coadjacent plate Will be provided on both of its lateral faces with laterally-projecting tongues or ridges Which engage in the grooves of the coadjacent plates and as the blocks so constructed are alternate inA position with respect to each other throughout the.' circumference ofthe tire, interengagement and coperation is effected and each plate'is complemental to a coadjacent plate.

I {claims- AlifAveliicle tire of the block type adapted to 4bepositioned on the felly band of a vehicle Wheel comprising a plurality of metallic plates, all of said plates triangular in outline and disposed With apices. alternating With the bases of coadjacent blocks, a portion of said plates provided on their lateral faces With grooves and the alternating plates provided With-lateral ridges arranged to interengage with the grooves of the other plates, all of said plates provided With resilient blocks secured thereto.
